The Miles City Field Office manages more than 2.7 million surface acres of public land and over 12.4 million acres of subsurface mineral estate in eastern Montana. This area of responsibility includes 16 counties in eastern Montana.

This area’s fossil resources are world famous for well-known dinosaurs such as Tyrannosaurus Rex, Triceratops and Hadrosaur—made famous by Hollywood and the media. Each year, these world-class specimens attract field excavation crews from federally-recognized fossil repositories, museums and institutions from across the U.S.

Our priorities are to cultivate community-based conservation and citizen-centered stewardship. When visiting Montana, be sure to visit the high plains and discover for yourself "Montana’s Best Kept Secret."
